IMPROVEMENT IN METHODS OF EXTRACTING THE SALTS 0F AMMONIA FROM COAL-GAS.

Specification forming part of Letters Patent No. 152,913, dated July 14,1874; application filed January 14, 1874.

To all whom it may concern Be it known that I, PETER MUNZINGER, of thecity of Philadelphia, State of Pennsylvania, have invented an Apparatusfor Bemoving Ammonia from Illuminating-Gas, of which the following is aspecification:

The gas in its passage is caused to flow through one or morepurifying-chambers, which are heated by coil heating tubes of anydescription, either cylindrical, conical, or tapering. The tubes atomizeand heat the gas to the required degree, whereby its ammonia is removedand precipitated.

Figure 1 is a vertical section of an apparatus designed to illustratethe invention. It has conical heating-coils in this instance. Othercoils can be used, either cylindrical, tapering, or of a shape suited toconvenience or necessity. Fig. 2 is a plan view.

A is a fluid and precipitating chamber, to which connect thecommunicating purifyingchambers B B and the single purifying-chamber B 0is the gas'inlet pipe, from the hydraulic main of the works, and D theoutletpipe. E E E are conical coil heating-andatoniizing pipes in thechambers B B B They are supplied with steam and exhausted by the pipes FF. The gas enters at the pipe (3, and, following the direction of thearrows, passes out at the pipe D. In its passage through the chambers 13B 13 it is thoroughly atomized by the coils, and every particle isbrought in intimate contact with their heated surfaces, which raises thetemperature of the gas to the required degree, whereby the salts ofammonia are removed and precipitated in the vessel A.

The invention consisting, as shown, of one or more purifying-chambers,in connection with coil heating-pipes, I, therefore, wish it distinctlyunderstood that I do not confine myself to the chambers or pipes B 13-13 as shown. Neither do I confine myself to the number of chambers andcoils to an apparatus.

I claim as my invention- 1. A coil heating-pipe, in combination with aheating-pipe or purifier, for the purpose shown and described.

2. The combination of a precipitatingvessel,A, a heating chamber orpipe, 13, and a coil heating-pipe, E, for the purpose shown anddescribed.

In testimony whereof I hereunto sign my name in presence of twosubscribing witnesses.

PETER MUNZINGER.
